FIELD OF THE DISCLOSURE

The present disclosure relates generally to communication systems, and more particularly, to the enhancement of public safety communication systems through linkage with additional non public safety communication devices.

BACKGROUND

Public safety personnel, such as police officers, firefighters, paramedics and the like typically utilize numerous communication devices while working in the field. Public safety communication devices include, for example, mobile radios such as handheld radios and/or vehicular radios along with remote accessories, such as remote microphones, speakers, earpieces, headsets and the like. These primary, mission critical devices and the infrastructure to support their operation are typically realized in the form of a narrowband system operating via a private network governed by a public safety agency.

Public safety personnel often carry additional non-mission critical devices, such as cell phones, personal digital assistants, electronic notepads and the like which operate over a broadband connection. These secondary, non-mission critical devices do not provide a user interface for high stress environments and can become a distraction to the user during a mission critical situation. Particularly in high stress emergency situations, the ability to manage numerous communication devices can become problematic.

Accordingly, there is a need for an improved communication system which will alleviate the aforementioned problems associated with managing numerous communications devices.

Briefly, referring toFIG. 1 there is shown acommunication system100 formed and operating in accordance with an embodiment of the invention.Communication system100 comprises apublic safety network140 and abroadband system150. For the purposes of this application thepublic safety system140 provides aprivate narrowband network110 governed by a public safety agency. In accordance with the embodiment, thepublic safety system140 also comprises a dispatch andinformation management center124 and at least one publicsafety communication device102 operating over theprivate narrowband network110.Broadband system150 is formed oftraditional network infrastructure126 operating over a private orpublic network112 andbroadband system150 also includes at least onebroadband communication device104, which typically operates as a non public safety communication device.

The at least one publicsafety communication device102 and the at least onebroadband communication device104 provide a plurality of communication devices for asingle user106 which are preferably handheld devices or devices worn on or about the user's body so as to be under the immediate control of the user. For ease of description and consistency, the plurality of communication devices will be referred to asnarrowband communication device102 andbroadband communication device104.Narrowband communication device102 comprises a public safety narrowband transceiver and controller with user interface elements comprising for example: microphone, loudspeaker, and display. Examples ofnarrowband communication device102 include but are not limited to: hand-held or bodily worn two-way narrowband radios operating under a public safety agency, emergency response rescue groups, and the like.Narrowband communication device102 further comprises personal area network (PAN) connectivity (examples: Bluetooth, WLAN, Zigbee).Broadband device104 comprises a broadband radio transceiver, controller and user interface elements such as microphone, speaker, display and the like. Examples ofbroadband device104 include but are not limited to: a cell phone, a personal digital assistant (PDA), an environmentally designed device to name a few.Broadband device104 also includes personal area network (PAN) connectivity (examples: Bluetooth, WLAN, ZigBee).

In accordance with an embodiment, a local network subsystem is integrated within thenarrowband communication device102 and thebroadband communication device104 to provide paired devices operating in a peer-to-peer manner over amaster-less communication link120 using the PAN. The local network subsystem defines a set of communication elements linked together for an interconnected peer to peer (vs. traditional master/slave control) network. Themaster-less communication link120 coordinates the management of the plurality of paired communication devices such that thebroadband communication device104 provides additional public safety applications to theuser106.

Asecure network link122 is provided to link the dispatch andinformation management center124 of thepublic safety system140 to thetraditional network126 of thebroadband system150. Thesecure network link122 may be implemented using for example, a public/private long term evolution (LTE) system or other appropriate technology, thereby allowing data and in-field device status between thepublic safety system140 andbroadband system150. Once the devices are paired,broadband communication device104 operates as a partner communication device to narrowbandcommunication device102 in response to predetermined public safety triggers, which may occur at either device. When operating in a public safety mode of operation, the broadband device will be referred to as thepartner device104.

In the public safety mode of operation, thenarrowband communication device102 operates user interface elements, information management, event management applications, and connectivity with thepartner device104 for sharing contextual information. Examples of contextual information include but are not limited to: radio status, sensor status, ambient sound, location and the like. In accordance with an embodiment, thebroadband device104 when operating as a partner device provides expanded user interface elements, along with information management, event management applications, and connectivity to other local devices.

In accordance with an embodiment,communication system100 provides interconnectivity between thenarrowband communication device102 andbroadband communication device104 by providing aninformation sharing link120 between the devices that coordinated intelligent information sharing to leverage key functions at each device.Communication system100 provides further interconnectivity between thenarrowband communication device102 andbroadband communication device104 by providing thesecure network link122 between thepublic safety network140 andbroadband system150. The interconnectivity is controlled by applications targeted to safety and productivity aspects associated with the public safety user responsibilities and job role.

The interconnectivity ofinformation sharing link120 controls: local or personal area connectivity (Bluetooth, WLAN, ZigBee, etc), control of a color display, intelligent lighting, time out timers, operating system (OS) level event driven triggers, power management, user interface, event sharing protocols, and public safety wide area voice or integrated voice and data protocols (example: APCO 25 protocol). The interconnectivity ofsecure network link122 controls the proper routing of information from thebroadband device104 into the device(s) in the narrowband system using the dispatch andinformation management center124. Information sharing link120 controls interconnectivity via at least one of: general event sharing, coordinated event sharing, coordinated bi-directional event sharing, and both application and event sharing.

In accordance with an embodiment, thecommunication system100 defines a set of communication elements linked together for an interconnected peer to peer (vs. traditional master/slave control) network. The linked elements support public safety information and status sharing to facilitate user interaction, increase user awareness, and enhance safety via automation of interaction betweennarrowband communication device102 andpartner device104. Examples of a status sharing comprise call mode, emergency mode, intelligent lighting mode, menu mode, scan mode (vs. idle mode) to name a few. The status and the context of the status can be shared via at least four status sharing methods comprising general event sharing, coordinated event sharing, coordinated bi-directional event sharing, and both application and event sharing to be described later. The linked elements operate under a safety net application that controls the delivery of additional safety information to and from thenarrowband communication device102 andpartner communication device104. The safety net application ensures that information is sent to the most appropriate device (or the most appropriate element on a device) and shared in an acceptable format. The additional information facilitates responses that lead to added user safety and work efficiency.

The addition of a partner device or partner devices that is not limited by the resource constraints or bandwidth constraints of a traditional narrowband public safety network allows for parallel operation that increases information between the dispatch andinformation management center124 anduser106, for example a field officer. The combined sharing expands traditional capabilities of thenarrowband communication device102 as the two (or more)devices102,104 operate in a collaborative manner.

Thecommunication system100 operating in accordance with embodiments of the invention protects independent device to independent device (narrowband communication device102 and broadband communication device104) synchronization of event occurrences to trigger additional local device activity. The “linkage”120,122 provides for an equal level of sharing. The sharing and linkage of elements within thecommunication system100 allows certain elements, such as for example display, loudspeaker, and keyboard, to not have to be duplicated on multiple devices, thus lowering overall cost of the system without loss of overall functionality.

In accordance with an embodiment, device interconnectivity can be classified under four general categories: general event sharing, coordinated event sharing, coordinated bi-directional event sharing, and both application and event sharing. A discussion of each category is provided below:

• General event sharing—One peer device (example: public safety radio) initiates a certain activity and transmits its status or event trigger out to another peer device (example: PDA). The first device processes the event indifferent to the activities of the second device.
• Coordinated event sharing—One peer device (example: public safety radio) initiates a certain activity and transmits its status or event trigger out to another peer device (example: PDA). The first device processes the event with the understanding of the capabilities of the peer device so that optimized responses occur. For example, the radio can save battery power if the PDA has an available or better communication transmitter or more battery power.
• Coordinated bi-directional event sharing—One peer device (example public safety radio) initiates a certain activity and transmits its status or event trigger out to another peer device (example: PDA). The first device processes the event with the understanding of the capabilities of the peer device so that optimized responses can occur. For example, the radio can save battery power when the PDA has an available or better communication transmitter or more battery power. Additional interaction or trigger event information is shared between devices post event. For example, the interaction between the two devices causes an audible alert to turn off one both devices or trigger a follow-on functional change in the originating device—in this example, the originating device being the radio.
• Both Application and event sharing—One peer device (example: radio) initiates a certain activity and transmits both application code and status or event trigger information to another peer device (example: PDA). The radio processes the event while the PDA device executes the received application code, and the PDA processes the event trigger. The device interaction can mirror the prior three interaction scenarios. This approach allows for the initiating device (example: radio) to know exactly how the second peer device (example: PDA) will actually process the events.

Referring back toFIG. 1, in operation the plurality ofcommunication devices102,104 each includes a local network subsystem, the local network subsystem automatically assembles the master-less wireless network among the plurality ofcommunication devices102,104 using at least one channel for information transfer as indicated byinformation sharing link120. In accordance with an embodiment, a plurality of predetermined applications are stored within dispatch andinformation management center124 of the narrowband network, accessible by the local network subsystem. Dispatch andinformation management center124 stores and downloads predetermined applications to the local network subsystem based on the information transferred amongst the plurality of plurality ofcommunication devices102,104. The downloaded application(s) control transmit and receive functionality based on the transferred information content. The previously discussed safety net is created by gathering as much information content as possible from people and devices in the field and utilizing this information for better safety support decisions and increased information deployment to the field.

FIG. 2 shows an example of a moredetailed communication system200 operating in accordance with an embodiment of the invention.Communication system200 comprisesnarrowband communication device102 operating over the privatenarrowband network110 andbroadband communication device104 operating over the private network (or public network)112 as described inFIG. 1. In accordance with an embodiment, information and applications are shared with thenarrowband communication device102 via the public safety system from dispatch andinformation management center124 having an information andapplication database264. Public safety information collected via the publicsafety radio device102 can be shared with the dispatch andinformation management center124 via thenarrowband network110. If information can not be shared via thenarrowband network110, thebroadband communication device104 can act as an RF modem to route data via thebroadband system150 oversecure network link122. The information and applications may also be stored locally at anoption board230 and then downloaded to thenarrowband communication device102. Thebroadband communication device104 receives the applications over thesecure network link122 and can share the information and applications withnarrowband device102 via a personal area network (PAN) overinformation sharing link120.

The applications downloaded to thenarrowband communication device102 provide the collaborative interaction to be used amongst devices. Additional information referred to as context information surrounding the user and devices is also gathered. Context information can be gathered, for example by sensors, such as portable andstationary sensors242,biometric sensors244, and/or wireless body wornsensors246. Context information can also be gathered by location tracking technology embedded within thecommunication devices102 and/or104. The context information can be shared with the dispatch andinformation management center124 via narrowbandprivate network110 or via private/public broadband network112.

For example, dispatch andinformation management center124 may download an application that controls the collection of sensor data at thenarrowband communication device102 for a narrowband device having sensor capability, such as a portablestationary sensors242 and/orbiometric sensors244. The public safety information is managed by applications onradio102 and can be mirrored and communicated viabroadband devices104 for redundancy.Broadband communication device104 can also receive sensory information from the sensors, such as thebiometric sensors244, over aBluetooth link248, or Zigbee or other PAN link.

From a vehicular perspective, avehicle250 comprises wireless controls252 and in-vehicle docking station254 for gathering information from acontrol group256 and gathering information from in-vehicle sensors258. This information is transferred over the privatenarrowband network110 for communication to adispatch center260 andnarrowband communication device102.

In accordance with an embodiment, thedispatch center260 is shown communicating with the private narrowband network of the public safety system and the private/public network112 of thebroadband system150. While thedispatch center260 normally interfaces with the private narrowband network of the public safety system140 (as part of dispatch and records management center124), in this embodiment the downloading of the applications fromnarrowband communication device102 tobroadband communication device104 enables thebroadband communication device104 to temporarily communicate withdispatch center260. Other types of dispatch centers or control centers, such as vehicularincident command center262, may also provide control services to private orpublic network112 of thebroadband system150 and privatenarrowband network110 ofpublic safety system140.

FIG. 3 is a diagram illustrating an example of information andapplication dissemination300 amongst communication devices operating within the communication system in accordance with an embodiment of the invention. Downloadable information and applications comprise context information pertaining to missioncritical applications302,efficiency applications304, andvehicular network applications306. Integratedvehicular network applications306 operate in conjunction with bothapplications302 and304. Modules integrated within or operating withnarrowband communication device102 include sensors, Bluetooth capability and internet-network capability for internet and network connections. The context information pertaining to missioncritical applications302 comprise for example, Bluetooth secure pairing, GPS and location applications, Man-down emergency applications, biometric sensor, and chemical monitoring.

Efficiency applications304 comprise, for example, back-up push-to-talk (PTT) and emergency features, running public service announcement (PSA), rules for RF ID tracking, drivers license tag reader, camera capability for facial recognition and identification, text-to-speech prompts and WLAN broadband capability. As mentioned previously, thebroadband communication device104 can operate as an RF modem for PTT audio originating from thenarrowband communication device102.

Examples of the vehicular network applications include but are not limited to: mobility measure of P25 broadband links, in-vehicle docking station for portable devices, modular wireless vehicle console, mobile information HUB, touch screen user interface, and video, such as up-link and down-link video.

Thecommunication systems100,200 andapplication dissemination300 provide the ability to develop and deploy abroadband communication device104 to operate as a partner device to thenarrowband communication device102 to increase safety and productivity of the user. Thebroadband communication device102 strengthens the safety net and compliments the core radio devices. In-field support is enhanced by the automatic selection of appropriate device for a particular action based on predetermined rules as set out in the downloaded applications.

The communication system allows for the placement of a function on the most reasonable device; however the feature affects all linked devices. Thus, a safety enhancement is provided without additional material costs. For example, utilizing the simplest/fasters device for a given task, a public service personnel worker can better focus on the job at hand. Additionally, by adding the cross-linkage capacity to a higher level of features, the collaborating devices are able to support an ever-changing environment surrounding the user. Operational features can also be escalated based in the radio and radio user's current situation—as determined by the context information.

As an example, considernarrowband communication device102, such as a two-way radio, going into emergency mode, thepartner communication device104 being altered to the radio mode automatically enables voice recognition. Commands from theuser106 are then received by thepartner communication device104 and routed back to the radio. As such, the radio is not expending battery power or processor power for this voice feature.

FIG. 4 is aflowchart400 providing an example of event processing between two paired communication devices operating in accordance with an embodiment of the invention. For this example, the paired devices will be referred to as paireddevice1 and paireddevice2402,408. An event occurs at404 (for example: a call, an emergency button press, or the like) at paireddevice1. Paireddevice1, in response to the event,shares406 pertinent information pertaining to the event details with paireddevice2. At410, paireddevice2 processes the event details as well as any other pertinent information supplied bydevice1 or collected by device2 (for example, location or sensory data as configured by missioncritical application302 ofFIG. 3). The event information is also processed by paireddevice1 at412. Process event details atdevice2 are shared at414 in conjunction with the configuration application232. Additional information, if any, (for example: location and sensory data), is also processed bydevice1 at416. Processing of the information at bothdevices1 and2 is ended by time-out timers at418,420. Thus, by sharing the processing event in conjunction with additional contextual data, the best device can now be automatically used for certain functions. The sharing occurring between406/410 and414/416 can be configured based upon: controlling general event sharing, coordinated event sharing, coordinated bi-directional event sharing, and both application and event sharing as discussed previously.

The process ofFIG. 4 provides improved data response efforts shared between paired narrowband and broadband devices. There may also situations where thenarrowband communication device102 can inform thebroadband device104 of an issue, thedevice104 informs the radio that will assume certain feature responsibilities; and together the two devices have overcome a fault, error, or environmental issues without user interaction.

FIG. 5 is aflowchart500 example of information sharing and event triggering for the interaction of devices operating within the communication system in accordance with an embodiment of the invention. The interaction begins by device pairing at502. Device pairing can occur using or in response to manual and known product pairing associated with the type of selected PAN technology. In accordance with this embodiment both thenarrowband communication device102 andbroadband device104 enable their respective information sharing applications at504 and506. In accordance with this embodiment an information sharing link is authorized at508. The basis for authorizing the information sharing link can include backend authentication of a second level paring event, if desired. Theauthorization508 creates a baseline for other event activity, such as sharing radio functionality, sharing radio profiles, such as operating modes. In accordance with the embodiment, at510 thebroadband device104 user interface is linked to the status ofnarrowband communication device102.

At512 a determination is made whether an event trigger occurs (for example an emergency event). If no event is triggered, the broadband device displays event context information pertaining to the narrowband communication device at516. This allows processing power and battery power to be saved atnarrowband communication device102. Thebroadband device104 follows predetermined rules during the local interaction with thenarrowband communication device102 allowing for an expanded user interface for the user. the predetermined rules also include rules for sending and receiving information between the two devices in a collaborative manner.

If an event trigger occurred at512, then an event application download occurs at514—the event application download corresponding to the type of event occurring. For example, an emergency application download enables emergency operating features. The emergency application can enable interface features such items as enlarging fonts on a display, intelligent lighting, and matching of narrowband communication device profiles for the emergency application. The event which caused the trigger is processed at518. The event processing can be controlled though one or more of: user interaction, received interaction (from thepartner device104 or external device), radio application interaction, and transmit interaction (for example to confirm the event).

The processing of event triggers and responses occurring at512.514,518 can be further exemplified by device triggers and responses shown inFIG. 6 as602,604. InFIG. 6, a table600 provides examples of such device activity. Table600 shows several examples of radio event triggers602 received bynarrowband communication device102 andresponses604 by the partneredbroadband communication device104. For example, aradio event trigger606 of receiving an emergency alert, call alert, private call or group call can result in the partneredbroadband device response608 of: user interface being matched to the radio; intelligent lighting operation; requesting further detail; displaying information; and providing visual, audio, or haptic feedback. Aradio event trigger610 of emergency initiated based on sensor data, such as a man down sensor, can result in partneredbroadband device response612 of: broadband device records in audio and/or visual format; utilization of the broadband connection to deliver additional information and enabling of location determination and voice recognition, “take a picture” to force camera activity with log time, recording an audio stream, sending a back-up request message or emergency group call.

Additional responses may occur at both devices in response to the radio event trigger. For example, aradio event trigger614 of secondary sensor processing can result in: the narrowband device submitting an application, module, or sensor identification to the broadband device, the narrowband device may stream the sensor data to the broadband device, and the broadband device may link the streaming data to other monitoring applications at616.

Another event trigger example may be an out ofrange indicator618 occurring at thenarrowband communication device102, which results in aresponse620 of thebroadband device104 echoing the narrowband device's audio stream into thetraditional network126 where the audio is then sent to thedispatch center124 via thesecure network link122 allowing for communication when thenarrowband device102 is out of system range.

An event trigger ofchannel change622 at the broadband device can result inseveral responses624 such as: posting the channel information to the broadband device such that the broadband device shows the channel information in a large font or the broadband device lists out any additional information, such as the most recent or common active users a talkgroup.

A low batterytrigger event trigger626 at the narrowband device can result in aresponse628, such as the narrowband device alerting the broadband device of the radio's low battery condition, the broadband device alerting the narrowband device that it is taking over certain operations, and the narrowband device converting to an out of range condition with transmit disabled for power savings.

Independent use cases can still occur with and without the partner device. In either scenario, the user can still accomplish a base level of acceptable functionality on either device (as if there were no linkage). The inclusion of the additional data processing increases user knowledge and understanding via system driven contextual information. Likewise, providing the user's local user contextual information to a dispatcher or secondary group (for example: supervisor) propagates safety information throughout the system to other users and groups.

The broadband communication device can also transmit triggers back to the radio, when the radio is properly configured. This interaction can create a type of remote control unit for the radio where the user can leverage, for example, the voice control and touch screen abilities of the second device to change channels, initiate events (status/message), or enhanced input method for text messaging. These control methods between the 2-to-n devices can be managed via understood languages such as extensible markup language (XML), pre-defined parameter commands, prior known serial commands or other data packet based over the air command protocols.

The communication devices operating in accordance with the embodiments work together for increased self-coordination, adjusting device responses based on surrounding context information, and controlling the which function gets assigned to which device increases user safety. The automation of information delivery to both devices allows for a single communication device, such as a radio or PDA, to be selected to automatically handle certain functions.

EXAMPLES

The following examples describe various embodiments of partnered device interaction for the communication system operating within a public safety environment. For the following examples, the first device is thenarrowband device102 operating within a public safety system and is referred to as a radio, while a second device is thebroadband device104 operating in either a private or public network within a broadband system and is referred to as a personal digital assistant (PDA).

Example #1Call Received

• • Radio identifies a peer device and vice versa
  • Devices associate either with a proprietary or common standards based protocol (example: Bluetooth)
  • Post association, the devices share a functional list in some understood proprietary protocol (example: XML)
  • Radio receives a call from a specific user
  • The two devices can manage this event in three different ways in accordance with the device interaction scenario.

DeviceInteraction Scenario #1

• • Radio shares that radio ID with a second device (example: PDA) and processes the call indifferent to the fact that the radio shared the information with the PDA; i.e. radio enables intelligent lights, and any applicable tones
  • Second device (example: PDA) utilizes the caller ID and the fact that the Call Receive event occurred to process additional activity
  • The PDA processes any call receive audible tones and enables the call receive intelligent lighting for some pre-set of time (i.e. time-out-timer)
  • PDA engages the Customer Enterprise Network (CEN) to acquire additional information about the user associated with the received caller ID (location, current status, skill-set or linked work apparatus)

DeviceInteraction Scenario #2

• • Radio shares that radio ID with a second device (example: PDA) and processes the call without audible tones or intelligent lighting to save battery life of the hand held mission critical device. (Additionally, no GPS location update or other events need to occur if the PDA will process the same event details)
  • Second device (example: PDA) utilizes the caller ID and the fact that the Call Receive event occurred to process additional activity
  • The PDA processes any call receive audible tones and enables the call receive intelligent lighting for some pre-set of time and any GPS location update or other events needed for this event
  • PDA engages the Customer Enterprise Network (CEN) to acquire additional information about the user associated with the received caller ID (location, current status, skill-set or linked work apparatus)

Device Interaction Scenario #3

• • Radio shares that radio ID with a second device (example: PDA) and processes the call without audible tones or intelligent lighting to save battery life of the hand held mission critical device. (Additionally, no GPS location update or other events need to occur if the PDA will process the same event details)
  • Second device (example: PDA) utilizes the caller ID and the fact that the Call Receive event occurred to process additional activity
  • The PDA processes any call receive audible tones and enables the call receive intelligent lighting for some pre-set of time and any GPS location update or other events needed for this event
  • PDA engages the Customer Enterprise Network (CEN) to acquire additional information about the user associated with the received caller ID (location, current status, skill-set or linked work apparatus)
  • The PDA can transmit alert information back to the radio for additional audible or visual alerts if required (example: radio alert occurs if the call was located within a pre-set radius of ¼ mile) or ensure that the radio exits a call alert tone.
    • An example of this can also been seen as a feedback loop between the radio and PDA such that if the radio receives a call alert and both devices make an audible tone, acknowledging the tone on the radio terminates the tone on the PDA or vice versa.

Device Interaction Scenario #4—Extensions of Prior Device Interaction Scenario Descriptions

• • This scenario could be any of the prior scenarios accept that at the initiation of the radio event (call alert) the radio downloaded specific PDA application code that instructs the PDA how to react to the trigger event and associated caller ID information.

Example #2Remote Control

• • Radio identifies a peer device and vice versa
  • Devices associate either with a proprietary or common standards based protocol (example: Bluetooth)
  • Post association, the devices share a functional list in some understood proprietary protocol (example: XML)
  • Second device (example: PDA) offers an application that can drive events on the radio device
    • Channel changes, volume control, call initiation, etc.
  • The different DIS procedures would vary with the coordination of the radio LEDs or color display showing the channel change or call initiation event.
    • The call initiated from the PDA would still be controlled on the radio via the time out timers
    • The radio would be capable of communicating its internal status (i.e. result of the call time out timer) back to the PDA

Example #3aRadio Emergency Button

• • Radio identifies a peer device and vice versa
  • Devices associate either with a proprietary or common standards based protocol (example: Bluetooth)
  • Post association, the devices share a functional list in some understood proprietary protocol (example: XML)
  • When an emergency is initiated on the radio, the device focuses on transmitting the emergency out to the mission critical network and dispatcher
  • The second device (example: PDA) . . .
    • Switches to a larger vector font on the display
    • Transmits location update via a second network (example: broadband) so as to not interrupt the radio transmitting the emergency indication
    • Enables voice recognition and video and audio recording can initiate

Example #3bEmergency Sensor Response

• • Radio identifies a peer device and vice versa
  • Devices associate either with a proprietary or common standards based protocol (example: Bluetooth)
  • Post association, the devices share a functional list in some understood proprietary protocol (example: XML)
  • When an emergency via accelerometer, “Man-Down”, or sensor is reported to the second device (example: PDA), the PDA instructs the radio that it needs to enter emergency mode (alarm or call)
  • The two devices can work in redundancy such that
    • Both devices transmit emergency via different networks
    • Both units transmit sensor data over both networks
    • Both units transmit ambient audio via both networks
  • The list of functionality can be utilized for redundancy, selectable for power savings, intelligent based upon the amount of information and the capabilities of the different networks
    • Only transmit as little as possible on public safety device due to high transmit power compared to low power cellular or WLAN transmission
    • If out of range, the radio can defer transmission of typical mission critical data (emergency, call request, etc) over to second peer device if it has coverage
    • Depending on inter-network configuration, the second device (PDA) can utilize the radio vo-coder (example: speech coding within the advanced multi-band excitation AMBE standards) to encode PDA recorded voice so that it can be more readily re-inserted into the radio network via a simplified inter-system gateway.
      This last section of example #3b is applicable to any of the scenarios as it typifies the ability of the devices to work together for added benefit of:
  • Power Savings by only utilizing 1 transmitter (lower power) than using both
  • Appropriate network selection for greater efficiency (not taxing limited mission critical compared to available broadband)
    • Transmitter power needs compared to available battery can also be a factor
  • Ability to use elements on other devices for added benefit of size, shape, or battery requirements
    • Limited electrical elements
      • camera
      • additional CPU for MIPS intensive functions
      • Accelerometers, GPS, or dead reckoning elements
    • Utilization of form factors that better match specific data input
      • larger color display
      • qwerty keypad for data entry to any device
      • touch screen User Interface for single control entry
        The examples of various embodiments focus on public safety scenarios by focusing in emergency response details back to the dispatcher. While traditional approaches carry voice, the peer devices of the various embodiments can augment the audio with key dispatcher desirable information being transmitted without affecting the resource constrained public safety network elements.

The communication system provided and operating in accordance with the various embodiments comprises a plurality of mater-less hand held devices operating in a public safety environment providing mutual association, feature/function sharing and managed redundancy. Safety, power management and productivity as well as overall user experience are enhanced though the use of the collaborating devices. The enhanced communication system provides for the ability for greater decision making and automation of decisions in the public safety environment.

Accordingly, there has been provided an enhanced communication system for use in a public safety environment. The automatic coordination of decision ownership amongst public safety and non public safety devices is provided. The automated peer-to-peer networking amongst a user's hand-held and bodily worn products provides a seamless communication stream to the user thereby improving safety conditions in hazardous environments. The communication system allows for improved user interface without user interaction to provide for optimized relaying of public safety information over the public safety device and non public safety device.

The communication system operating in accordance with the various embodiments provides a valued connection between a narrowband device, such as a public safety radio, a broadband device, such as a data device, a private narrowband system, and a public or private broadband system. The separation of the two (or more) devices, as opposed to an all in one device, provides redundancy in that the secondary (partnered broadband device) device can fail but the mission critical communications will still continue using the primary narrowband public safety device. Additionally, the use of multiple devices allows for the separation of mission critical information from the detailed contextual information which might otherwise overwhelm the user in the public safety working environment. The collaborative processing and sharing of information allows for triggered inputs to enable changes across the multiple devices for shared device functionality. The communication system provides synchronization of status of the multiple devices to enable cooperative or independent operation based on events and surroundings. The interaction of the devices allows not only for content management but the automatic updating of operational features thereby improving the user experience.
